GENERAL SAFETY GUIDELINES
USING THE PRODUCT WITH METERING PUMP
Danger! In emergencies the pump and multi-valve should be switched off immediately! Disconnect the power cable from the power supply!
When using pump and multi-valve with aggressive chemicals observe the regulations
concerning the transport and storage of aggressive fluids!
When installing always observe national regulations!
Manufacturer is not liable for any unauthorized use or misuse of this product that may
cause injury, damage to persons or materials.
Caution! Pump and multi-valve must be accessible at all times for both operating and servicing. Access must not be obstructed in any way!
Pump , multi-valve and accessories must be serviced and repaired by qualified and
authorized personnel only!
Always discharge the liquid end before servicing the pump and multi-valve!

1. Introduction
Introduction:
Multifunction valve is a 4 functions device. It works as a “Anti-syphon valve”,
“Safety Valve” and “Bleed Valve”. Device can be set to operate at selected
pressures using knobs “S” and “A”.
Warning: Never turn knobs out of range!
Warning: Always connect discharge hose to multifunction valve!

NOTE:
Multifunction valve can modify the flow rate of the metering pump
connected.
Verify the pump flow rate after installing the multifunction valve.

2. Installation and Operating Modes
Multifunction valve installation:
- Unscrew junction-nut (1) from multifunction valve.
- Remove the hose connection kit from pump’s delivery valve. If pump is already installed
please read pump’s instructions-manual to avoid chemical injuries.
- Put junction-nut (1) on pump’s delivery valve. Be careful to the arrow direction on junctionnut(1) body.
- Place multifunction valve (turning discharge side as desired) on junction nut (1).
- Screw junction-nut(1) by turning it clock-wise until it’s completely locked.
Pressure valve operating mode:
“Pressure valve operating mode” keeps always closed the valve until is reached a specific
pressure value to the input. Pressure value may be set using the above procedure.
-Pull knob labeled “A” until it produces a “click”.
-Regulate pressure (bar) on desired value (within a range from 0 to 5bar).
-Press the knob labeled “A” until it produces a “click”.
Anti-syphon valve operating mode:
Anti-syphon operating mode avoid that dosing product goes through the injection valve
when the pump is not dosing because a negative pressure has been produced on the
injection valve.
-Pull knob labeled “A” until it produces a “click”.
-Regulate pressure (bar) on 0bar.
-Press the knob labeled “A” until it produces a “click”.
Note: If product’s tank is installed above the injection valve adjust knob (A) calculating the
height (0,1bar per meter and adding 1bar).
Safety-valve operating mode:
Safety-valve operating mode activates product discharge through discharge hose when is
over-reached a specific pressure value (max 18bar). Manual discharge feature is also
available.
Automatic product purge on over-reached pressure value:
-Pull knob labeled “S” until it produces a “click”.
-Regulate pressure (bar) on desired value (within a range from 0 to 18bar).
-Press the knob labeled “S” until it produces a “click”.
Manual product purge:
-Pull knob labeled “S” until it produces a “click”.
-Turn knob on “BLEED”.
-Regulate the pump flow knob on 0 (zero).
-Press the knob labeled “S” until it produces a “click”.
-Wait until purge ends then rotate knob back on previous position.
-Press knob until it produces a “click”.
